Abstract
El objeto de la presente invención es aplicar la inserción de una marca de agua en un contenido recibido por un dispositivo cliente, en particular a contenido de video comprimido. La presente invención propone un método para insertar una marca de agua en un contenido comprimido cifrado por lo menos por una clave de contenido (clave de CA), dicha clave de contenido, así como también los datos de premarcado forman los datos del CAS, dichos datos del CAS están cifrados mediante una clave de transmisión y contienen por lo menos una firma para autenticar todos o parte de los datos del CAS, dicho contenido comprimido recibido por un dispositivo cliente comprende: - un decodificador (103) que tiene una entrada para recibir el contenido comprimido cifrado y una salida para producir un contenido comprimido, - un insertador de WM (104) conectado directamente a la salida del decodificado; dicho insertador de WM están conectados con el condicionador (200), dicho condicionador ejecuta los siguientes pasos: - recibir los datos del CAS, - descifrar los datos del CAS con la clave de transmisión, - verificar la firma de los datos del CAS y si la firma es válida, - transferir la clave de contenido (clave de CA) al decodificador (103) y los datos de premarcado al insertador de WM. - insertar una marca de agua mediante el insertador de WM, el contenido descifrado recibido por el decodificador usando los datos de premarcado y el identificador.
